What is the Malthusian Theory? Is the Malthusian Theory applicable today or not at all? Please explain

A graduate student, Dolt Colt, at The Best Western University synthesized a drug called Drug X and noted that it lowered blood cholesterol levels in mice. He tried to see if it works in humans. Is it:   Replicability   Reproducibility   Generalizability   Translatability   Transparency   Rigor

Macular degeneration is a serious disease of the eyes that can lead to blindness. A recent study suggeststhat nutrients such as lutein and zeaxanthin, found in green leafy vegetables, can slow the onset andprogress of this disease in humans. In the study, a group of 2000 older individuals were contacted throughrandom digit dialing and asked about their eating habits. (Macular degeneration usually manifests later inlife.) The group who ate green leafy vegetables fewer than two times a week had a significantly higher rateof macular degeneration (25% higher) than those who ate green leafy vegetables five or more times perweek. They also had a higher rate (5%) of cases that were considered severe among those who had thedisease.(a) Determine whether the study is an observational study or an experiment. Explain how you know.(b) If the study is an experiment, identify the control and treatment groups. If the study is observational,state whether it is a case-control study, and if so, identify…

I really need help with this biology question. Based on what you learned on the Scientific Method, what kind of experiment would you carry out to prove or disprove your Alternative Hypothesis H1?

Researchers at the Best Southern University wanted to test the same Drug X (which was available from a commercial source) in their study to see if it lowered blood cholesterol levels in mice.  Is it:   Replicability   Reproducibility   Generalizability   Translatability   Rigor   Transparency
